Translation of gelatine in German

Then we did a boat trip which started somewhere in the delta and ended somewhere else in the delta. Each couple received a boat and an elderly lady had to row. I did not feel comfortable with that.
We really felt like being in a stupid tourist attraction. The environment was very beautiful but the mass of people would ruin our special moments. Anyway we had one more surprise on the way back.
We left town and drove around the lake. Around 30 minutes after leaving we had a flat tire, which I changed immediately. That was very annoying as the rental company asked us to fix the flat tire.
